MACHINE FCR CUTTING ICI-z.

SPECIFICATION forming part of Letters Patent; No. 369,107, dated August30, 1887.

Application filed September 17, 1886. Serial No. 213,889. (No model.)

. burg, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Machine for Cutting Ice; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings,which form a part or" this specification.

My invention relates to a machine for cutting ice, the object being toprovide a Inachine of simple and durable construction, and operated by ahand-crank or by steam-power, if desired, whereby ice may be cut from apond or other places in straight lines. This I accomplish by means of acircular saw mounted on a suitable frame, together with certain otherdetails of construction and combination of parts, as will be fullyset-forth hereinafter.

In the accompanying drawings, .Figure l is aside elevation of myimproved ice-cutting machine, constructed in accordance with myinvention. Fig. 2 is a plan view ofthe same. To put my invention intopractice and give the same bodily form, I construct a pair of skids orsled-runners, a, attached together by a frame, b. Secured to this frameb, in suitable bearings, c, is a horizontal shaft, d, carrying a largepulley or belt-wheel, e, and having attached to one end a hand-crank, f.To this shaft d, I also hinge two arms, g, conneeted at the other end bya shaft, h, having secured thereto a large circular saw, t', and smallpulley j. IIhis pulleyj, I connect to the large wheel 'e by adriving-belt, 7c. To the lower end of the arms g, I attach two handles,l, which afford means for guiding the machine and pressing the sawz intothe ice, m. At the rear end of the frame b, I hinge one or more sharppieces, n,which remain atan angle 'with the frame b, and will allow themachine to be easily pushed forward, but not back. Secured to the frontshaft, d, is a small chain-pulley, o,which operates, by means of anendless' driving-chain, r, a star-shaped wheel, p, secured in properbearings at the base of the frame b, andaifords a means of propellingthe machine forward. i

The saw i and arms g, I suspend in any required position above the iceby means of a threaded prop, s, hinged to the rear of the frame b. A

In operation the operators raise the handles l, and thereby lift the sawzabove the ice and move the machine to the desired point to start from.The crank f is then revolved, which rotates the large wheel e and sawt'. The operator at the handles f now presses the same down, whichbrings the saw in contact with the ice, m, cutting its Way down throughthe same. The star-shaped wheel p at the base of the frame b grips theice and drags the machine forward, and the downwardly-projecting piecesn at the rear prevent any backward movement of the machine. In this waythe apparatus moves forward, cut-ting the ice, m, in a straight line.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

' An ice-cutting machine consisting of a sled mounted on runners, apropelling star-wheel between the front runners applied on a shaltlocated below the driving-shaft d and receiving rot-ation therefrom bymeans of an endless chain and pulleys, a shaft bearing a circular cutterand receiving'rotation from said driving-shaft, the vertically-movablearms g g, bearing at their rearl ends said cutter-shaft, the handles Z,attached to the arms, said arms being vertically adjustable at theirrear ends by means of a nut and screw, the latter being pivoted to therear part of the sled, and the pieces n n, hinged to the sled andadapted to resist backward thrust of this sled when the machine is inoperat-ion, all substantially as described.
